Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606256, here are decompositions:

379 + 31605877 = 31606256
433 + 31605823 = 31606256
499 + 31605757 = 31606256
673 + 31605583 = 31606256
739 + 31605517 = 31606256
907 + 31605349 = 31606256
937 + 31605319 = 31606256
1009 + 31605247 = 31606256

Showing the first eight; more decompositions exist.
